When trying to import a graphml file with APOC, a message is displayed to set apoc.import.file.enabled=true in the apoc.conf file. However, this should be done in the neo4j.conf file. I could not find the apoc.conf file anywhere, so decided to put it in the neo4j.conf settings instead and it worked. Anyhow, it would be nice if this line of code could be added automatically to the neo4j.conf settings!
